Imam Ja’far Sadiq (a.s.) narrates from his father that the Holy Prophet (s.a.w.s.) has made Congregation Prayer compulsory for those living in the neighborhood of a mosque and used to say, “Those who do not pray in congregation will not succeed in their business. I will order the muezzin to give prayer-call and order a personality from my Ahle Bayt, that is Ali, to take a torch in his hand and burn the houses of those who do not pray in congregation.”
